Question

two droplets coalesce ina single drop. in this process .
a) energy is liberated
b) energy is absorbed
c) energy does not change
d) some mass is converted into energy

Answer 1

Answer:

energy is absorbed........

Answer 2

Energy is liberated when two droplets coalesce into a single drop

Explanation:

Find - what happens to the energy when two droplets coalesce into single drop.

• The surface area of is decreased for the single drop formed when compared with two individual droplets.
• It is understood that the process of coalesce decrease the surface area.
• Also the surface area and surface tension are related with each other.
• When the area decrease, there will be a decrease in surface area energy and surface tension energy
• There is a change in energy, also the present amount energy is lesser than the energy before coalesce.
• Therefore , the energy is liberated when two droplets coalesce in single drop.
